How deep can standing water on the road be before a car can't pass through?

[AsherRose]

1. When the water level is below half of the tire height, the driver can first observe whether other vehicles are passing smoothly to determine if there are deep pits or obstacles on the road. 2. If the water level exceeds half of the tire height, do not force the vehicle to wade through, as the car's exhaust pipe is at this height. Forcing passage may cause water to enter the exhaust pipe, thereby damaging the engine. Precautions: Slow down or stop to observe, and never force your way through. Turn on the wipers in advance and enter the water slowly. Maintain steady throttle and drive at a constant speed in low gear. When driving on waterlogged roads, ensure that the vehicle has sufficient power.
